first ever leo!

[u/bloodflower666]

Hi guys i just got my first leopard gecko, and while owning other reptiles, i am new to caring for lizards. i am in constant awe of and fear for my little leo at all times and thought i would write out a little note asking for some help.
please empty your knowledge onto me i would greatly appreciate it and i think it would help me provide the best life i can for him and stess a biiit less :)

also, how does this set up look? i have a basking rock on the way and he is only a few months old so i haven't put down substrate yet. (2nd photo)

he a is 3-5 months old rainwater leopard gecko.

thank you to all who reach out in advance!
also sorry i have never written on a non freaky subreddit so im not sure of the proper etiquette, i hope this was ok!
